SPECIFICATION forming part of Letters Patent No. 655,729, dated August 14, 1900.

Application filed November 16, 1899. Serial No. 737,254. (No model.)

applicable to weighing-scales, and is more es-. pecially, though not exclusively, adapted to that class of weighing-scales known as pricescales, the objects being, first, to secu're'a more perfect means for exposing the indications. upon opposite sides for the inspection of clerk and customer; second, to provide an improved means for supporting the platform, whereby the parts are more readily adjusted and assembled, and, third, to improve the construction of the bearings of scales.

The invention consists in certain novel details of construction and combinations and arrangements of the parts, all as will be hereinafter described, and pointed out more particularly in the claims.

Referring to the drawings, Figure 1 is aperspective view of a scale embodyingmy invention, the platform or load-receiver being removed therefrom and stood on end at the side thereof.- Fig. 2 is a plan view of a corner of the subplatt'orm. Fig. 3 is an elevation view of the opposite corner thereof, party of the same being broken away for clearness. Fig. 4 is an elevation view of the corner of the subplatform shown in Fig. 2. Fig. 5 is an enlarged sectional plan view on line X X of Fig.

3. Fig. 615 an enlarged end elevation view of the left-hand end of the top part of Fig. 1.

Fig. 7 is an enlarged elevation view on line X X of Fig; 1, the extreme upper portion thereof being partly broken away. Figs. 8 and 9 are respectively side and end elevation views of the bearing-block.

In the drawings, 10 illustrates the scalebase, provided with the platform-supporting levers of the general or any desirable construction connected to the steelyard-rod 11, connected at its upper end to, the lever 12,

fulcrumed in the housing 13, supported near opposite ends upon the outwardlycurved columns 14, which columns are secured at their lower ends near opposite corners of the base 10.

Within the base 10 is mounted a subplatform-frame 15, having a'pair of downwardlyextending legs 16 at each of its corners, said legs 16 at each corner being connected in the instance shown in Figs. 3 and 4 by a crosspiece 17. Nearthe lower ends and between each pair of legs 16 is a metallic block 18, provided with an opening 19 therethrough near its top. Through each opening 19 is passed a rod 20, whose opposite ends occupy openings in the legs 16, said rod 20 loosely bearing in said opening 19orsaid openings in said legs 16. In thelower ends of each of said blocks 18 is cut a slot 21, Fig. 9, into which is placed a portion '22,.of agate, steel, or other suitable hard material, preferably agate', provided with tapering .sides 23,which converge downwardly, leaving the portion 22 thicker'at its top and thinner at its bottom on two sides, so that when the portions 22 are inserted into the slots 21 of their respective blocks 18and the walls of slots 21 pressed inwardly, said portions 18 being of brass or other suitable soft mate- 8o rialpreferably, though not necessarily, of such soft materialsaid portions 22 will be firmly held from dropping downwardly out of'slots 21 of port-ions 18 by the walls of said .slots 21 conforming to the keystone-shaped opposite sides of said portions 22, while greater pressure is applied to the edges of the walls of slots 21 of portions 18, which'overlap said keystone-shaped portion 22,"sothat the metal forming said overlapping edges will be pressed 0 around the corners of theportions 22 to form projections 24. for preventing the said portions 22 from being laterally displaced from said slots 21 at their respective portions 18.

Some of said portions 22 are adapted to be 5 provided with a substantially-V shaped;depressed bearing-seat to receive and accommodate the knife-edge of the load-receiving bearings 25 of the platform-supportinglevers, while others of said portions 22 are adapted to be provided with the substantially-flat bearing-seat, so as to obviate the necessity for accurately spacing apart several sets of legs 16 or the portions 22, pivotally carried thereby, thus facilitating the manufacture of the scale and its assembling by unskilled persons, who in use are frequently required to assemble the scale after being shipped or after being cleaned and for other purposes.

The bearing-pin 20,'whieh pivotally supports portions 18 relatively with the legs 16, is at right angles to the pivots of the platform-supporting levers, while in the instance shown in Figs. 3, 4, 8, and 9 the opposite Walls of slot 21 in each of said portions 18 are parallel to and on opposite sides of their relative pivots 25, thus leaving between said projections 24, Fig. 5, an opening in each of said portions 18, through which practically all of the opposite ends of the portions 22 are exposed to view.

The ends of the legs 16 project below the lower edges of the walls of slot 21 and of pertions 22, and in order to prevent the knifeedge of the load-receiving pivots 25 of the platform-supporting levers from entering the joint between the downwardly and inwardly converging walls of the slot 21, Figs. 3 and 4, a projection 26 extends inwardly from the bottom of each of said legs 16, and the inner ends of said projections 26 project substantially over the edges of the portions 22, so as to prevent said knife-edge of pivots 25 from accidentally getting into the joint between said walls of slot 21 in portion 18 and the opposite sides of portion 22, while in order to deflect said pivots 25 from said portions 26 and into the bearing-seats formed in said portions 22, should said pivots accidentally contact with said portions 26, said portions 26 are formed on their lower sides with an upwardly and inwardly converging surface, and in the instance shown in Figs. 3 and 4 said portions 26 are given said upwardlyand inwardly converging angle by being formed of relatively flat strips secured to the upwardly-beveled inwardly-eonverging bottoms of the legs 16.

Upon each corner of the subplatform 15 is a rest projection 30, having projecting therefrom a pin 31, occupying a relatively-small portion of the surface of said projection 30, the tops of said pins 31 being tapered toward a point, as shown in Figs. 3 and 4, and adapted to rest upon the top surface of said projections 30 is a platform or load-receiver 32, Figs. 1 and 4, provided upon its under side with recesses 33, adapted to be occupied by said pins 31 when said platform 32 rests upon said projections 30 and said projections 30 raise said platform from above the ordinary unfinished top surface of the subplatform 15. ing of the pins 31 upon the top surface of the projections 30 further simplifies the machining of the holes 33 in the platform 32, so that a combined drill and counterbore may be used for forming said holes in the platform 32 when said platform is of metal or other substance that can be drilled and by the same operation machine the bottom surface of the platform 32, surrounding said openings 33, so

This form-' as to form a finished surface in the proper plane, so that said finished surface surrounding said recesses may firmly and evenly rest upon the top faces of projections 30,while pins 31, entering the recesses 33, prevent said platform 32 from being displaced laterally with relation to the subplatform 15.

In the instance shown in Fig. 1 the righthand end of the housing 13 is provided in its top with a slot 35, over which is secured an arm 36, Figs. 1 and 7, which arm 36 is connected through said slot to a loop 37, in which is fulcrumed by knife-edged bearings 38, Fig.7, the end of lever 12, near the center of which lever 12 is pivotally connected the upper end of rod 11, which construction is more fully shown in my Letters Patent No. 625,798, for a price-scale, dated May 30, 1809, in Figs. 1 and 8 thereof, the top construction thereof being similar to said construction shown in said Letters Patent, except that the poise M of said Letters Patent slides upon agraduatcd bar in its movement to designate the different rows of price graduations upon the price-indicating chart E of said Letters Patent, (shown more clearly in Fig. 7 of said Letters Iatent;) but in my present invention said poise M slides upon a substantially-vertical bar 40 unprovided with indications and 5c cured by angle-irons -11 to opposite ends of the casings F and K or otherwise secured. Adjacent said bar 40 and on opposite sides thereof and arranged at an angle therewith and substantially tangent to the casings F and K are bars 42 and 43, graduated to indicate weight or otherwise, said bar 42 being arranged adjacent and, in the instance shown in Fig. 1, above the slot in casing K, through which the price graduations upon the chart E are adapted to be exposed to view, while secured upon opposite sides of said poise Mare indicating-pointers 44 and 45, respectively, each provided with an indicating projection 46 upon the edge of said pointers 4-4 and 45 adjacent the zero-mark upon said graduated bars 42 and 43, while the opposite edges of said pointers 44 and 45 are provided with projections 47, extending beyond said indicating projections 46 to hide from view the indications adjacent the indication designated by said indicating projection 46.

From the foregoing construction it will readily be seen that while the price indications upon the chart F. are indicated through the slot in casing K by the projection 50, Fig. 1, carried by said poise M, (which projection 50 is adapted to be similar to the projection of poise M, shown in Fig. 7 of the aforesaid Letters Patent,) together with the weight of the load indicated by indicating projection 46 upon bar 42 for the inspection of the merchant or his clerk, so that both the weight and the price of the load are simultaneously indicated, in addition thereto the weight of the load is simultaneously indicated to the customer by the indicating projections 46 upon the graduated arm 43, so that the inerchant or his clerk may know the weight of the load and the price to charge therefor, while the customer will simultaneously see the weight of the load. It will be observed that the bars 42 and 43 are adapted to be arranged at such an angle with relation to the bar 40, upon which poise M slides, that said bars 42 and 43 are substantially at right angles to the line of vision, thus enabling the graduations upon said bars 42 and 43 to be readily read, which reading is facilitated by the projection 47, extending below and to one side of the indicating projection 46. A further object of this structure is to prevent the wearing action of the sliding poise M from scraping or wearing the graduated face of the bars 42 and 43.

Having now so fully described my invention that others skilled in the art may make and use the same, what I claim, and desire to secure by Letters Patent, is-
